Quartz Retarders These V-AR coated quarter-wave and half-wave plates are suitable fore high powers, having negligible absorption and very high transmittance. The low order single-plate design minimises angle and wavelength dependence whilst avoiding the very high cost of double-plate zero-order retarders
